I carry a Fenix E15 when I need a small flashlight with multiple brightness levels and a decently high "medium" setting as the default.
The brightness levels and tint are splendid and I prefer that the default setting is brighter than that on most other multimode lights. I like the lanyard attachment point, through which I installed a small split ring, then a short length of paracord. It can tail stand easily.
My only complaint so far is that my E15 is hard to use with just one hand. It is difficult to change modes when using only one hand due to the higher amount of torque required. Other than that, the quality is very good and I think it is smaller than the Olight model.
